2.1 Process Differences. Simultaneous Leaching and Adsorption: In CIL, leaching and adsorption occur simultaneously in the same step, whereas in CIP, leaching occurs first, followed by adsorption. Process Complexity: CIP has a relatively simpler process because leaching and adsorption are separate steps.

The first simulates the kinetics of gold/mineral leaching and estimates the total concentration of each element in solution during the leaching process. These total concentrations (for Cu, S, free cyanide, Fe, and Au) are the inputs for the speciation model, along with temperature and the initial pH, assuming the dissolved ions are in equilibrium.

Highlights Worldwide gold recovery on activated carbon grew from zero to almost 70% in twenty years from 1980. The stellar attributes of carbon gold plants led to complacency in the industry in designing and operating these plants. Most CIP and CIL plants are overdesigned and operated sub-optimally. Optimum design criteria and …

The first task is to measure the quantity of carbon in the various process stages. In carbon columns (CC) or strip vessels where only carbon is present, a direct volumetric measurement is possible. In carbon-in-pulp (CIP) or carbon-in-leach (CIL) systems it is necessary to obtain a sample from the agitated mix of carbon and pulp.

At this part, the applicability of CIL process in gold recovery with thiourea was investigated for the first time. As a result of the experiments, although higher gold leaching extents were obtained in CIL process, the increase in extent was about maximum 8% and the highest gold leaching extent was obtained as 75% at the end of the 5th hour.
